Description
Technical field
The present invention relates to senior Long Term Evolution (LTE-A, Long Term Evolution-Advanced) is drilled
Enter technology, more particularly, to a kind of reporting channel information method and terminal.
Background technology
Extensive antenna technology is one of LTE-A evolution and the guardian technique in following 5th generation (5G),
Third generation partner program (3GPP, 3rd Generation Partnership Project) the 13rd edition at present
An important issue " the Study on Elevation of RAN1 in this (R13)
Beamforming/Full-Dimension (FD) MIMO for LTE " mainly studies multiple-input and multiple-output
(MIMO) the further evolution in Long Term Evolution (LTE, Long Term Evolution).
Generally aerial array can be divided into two parts：Physical antenna array and transceiver channel array.Tradition
MIMO technology be based primarily upon the one-dimensional aerial array aerial array of level dimension (typically).Fig. 1-1
For the structural representation one of two-dimensional antenna array in correlation technique, as Figure 1-1, specifically, it
Physical antenna array 111 is probably the (physics in Fig. 1-1 of two-dimentional multiple-input and multiple-output (2D-MIMO)
Aerial array is that 8 row 8 arrange), but transceiver channel array 112 is the one-dimensional (transceiver channel in Fig. 1-1
Array is 1 row 8 row), multiple physical antenna a period of time of same row equipolarization are connected to same transmitting-receiving and lead to
Road.Phase contrast between the multiple physical antenna a period of time therefore only having level dimension is adjustable in, and vertical
Phase contrast between multiple physical antenna a period of time of dimension can not adjust, so traditional MIMO can only be
Level dimension carries out wave beam forming, and the beam shape of vertical dimension is the fixing (three dB bandwidth of usual vertical dimension
Less than 10 degree), in Fig. 1-1, Beam can only tie up adjustment direction in level, but the direction of vertical dimension is solid
Fixed (typically being determined by angle of declination).
FD-MIMO is based primarily upon two-dimensional antenna array, and (multiple antenna element of same row are connected to multiple receipts
Send out passage), Fig. 1-2 is the structural representation two of two-dimensional antenna array in correlation technique, as shown in Figure 1-2,
Specifically, its physical antenna array 122 and transceiver channel array 121 are all two-dimentional, extreme cases
Under as shown in Figure 1-2, physical antenna array and transceiver channel array are all 8 row 8 row, each physics sky
The corresponding transceiver channel of linear array, the phase contrast between multiple physical antenna a period of time that so not only level is tieed up
Can adjust, and the phase contrast between multiple physical antenna a period of time of vertical dimension can also adjust,
FD-MIMO can not only carry out wave beam forming in level dimension, and can carry out wave beam forming in vertical dimension,
In Fig. 1-2, Beam can not only tie up adjustment direction in level, and can adjust direction in vertical dimension.
Because user 123 (terminal 123) is distributed in differing heights in actual environment, particularly some high buildings
Scene, user 123 is larger in the distribution of vertical dimension, traditional base station be difficult to cover simultaneously high-rise and low
The user of layer, therefore FD-MIMO is more suitable for this scene that there is high building covering.
No matter traditional eNB is business beam or broadcast beam, the beam angle of its vertical dimension and direction are all
Fixing, in general vertical dimension three dB bandwidth is less than 10 degree, as shown in the left figure of Fig. 1-3, therefore works as reality
In the environment of border, user is when the distribution of vertical dimension is larger, and it is useful that traditional eNB cannot cover institute well
Family.Although FD-MIMO can form narrower business beam and can make in vertical dimension adjustment direction
Big beam direction points to user, but in order to cover the user of this cell differing heights as far as possible, such as Fig. 1-3
FD-MIMO shown in right figure need to form wider broadcast beam, because CRS, PDCCH etc. are public
Control signal depends on broadcast beam.
FD-MIMO is important directions of follow-up LTE evolution, and the advantage under high building scene is more
Greatly, it is therefore more likely that following can newly dispose a part of FD-MIMO eNB in some high building scenes, simultaneously former
Some tradition eNB also continue to retain.Thus can there is such a scene：May some in network
Base station is FD-MIMO eNB, and another part base station is traditional eNB, as Figure 1-4, for
FD-MIMO eNB, the vertical dimension 3dB width of broadcast beam larger (in order to cover the use of differing heights
Family), and business beam is narrower, can adjust beam position targeted customer in vertical dimension；For traditional eNB,
The vertical dimension 3dB width of broadcast beam and business beam is all narrower.
As a example following 1-4 figure, the Serving cell of UE1 belongs to traditional eNB, and FD-MIMO Cell is UE1
Adjacent area.When UE1 moves to position as Figure 1-4, the channel quality of neighbor data channel is better than
The channel quality of the data channel of Serving cell, but the adjacent area CRS_RSRP being measured due to UE1 is simultaneously
It is not better than the CRS_RSRP of Serving cell, that is, be unsatisfactory for event A3 (Event A3), wherein CRS_RSRP
Represent the RSRP based on CRS；Due to being unsatisfactory for event A3, according to existing standard, UE1 will not report
UE1 also will not be switched to adjacent area from Serving cell by measurement result, therefore network equipment, and it is really this
In the case of in order to obtain the better services quality of data, UE1 should be switched to from traditional eNB cell
FD-MIMO Cell, thus lift network performance.
